This whitepaper is intended to provide guidelines and best practice for information modellers creating OPC UA based information models. It is not a formal specification, i.e. it is not required to follow the recommendations in this whitepaper, but highly recommended.

The whitepaper is organized in several sections addressing different aspects of information modelling, from naming conventions to concrete modelling patterns for specific purposes.

The document is a living document, i.e. it will get extended with additional aspects over time and will be published at a higher frequency than specifications would be.

Note: This whitepaper describes the usage of various OPC UA modelling concepts. Not every Server has to use all those concepts, only the ones needed.
